After the recent update of M5s firmware to 1.25.42741.87953554 it does not disappear from the Google Home app and always appear "online" in that app. M5 still have the Chromecast version 1.28.102057 . In Google Home app has problems displaying what M5 is playing when you click on the speaker icon. If you click the media icon it shows whats playing but you cannot add other speakers (newer CC version required).
My A6 (that has no updated firmware) constantly disappear from the Google Home app. Only workaround is to power cycle but it A6 disappear after some time.
